, Application filed May 25, 1915. Serial No. 30,322.

To all whom it may concern Be it known that I, LOUIS Hint, a subject ofthe King of Hungary, residing at South River, in the county of Middlesexand State 1'. of New Jersey, have invented new and useof the permutativevariety.

One object is to provide a lock of the type described which cannot bepicked or opened unless the operator is familiar with the combination.

Another object is to provide a lock which is strong, light and cheap toconstruct.

These objects are attained by the novel construction and combination ofparts hereinaltterdescribed and shown in the accomoanvins; drawin formina material art of this specification'and in which:

Figure 1 is a side elevation of a padlock made in accordance with theinvention, shown in a closed position, the broken lines when partiallyunlocked. Fig.2 is an edge view of the same. Fig. 3 is'a side view ofthe lock, the cover plate being removed showingthe interior and the bowindicated in an open position by the broken lines, Fig. 4 is a verticalsectional view, taken on line 4L-i of Fig. 3, and Fig. 5 is a viewindicating the operation of the releasing block.

The main body 10, is preferably shield shaped in outline, with flangedintegral edges ll except or openings at the top for the ends of the bow12, secured by the pivot 13, which also passes through the cover 14:,further held in place by rivets 15 at various points as indicated.

One end of the bow 12, has an extension 16, reaching into the lookbeyond the pivot 13, and bearing against it is a flat spring 17 rigidlysecured to the inner side of the flange in such manner as to exert aconstant pressure tending to open the lock. The other end of the bow isformed with a hook 18 adapted to enter a narrow opening in the top ofthe flange and engage with adetent 19, pivoted at 20 and pressedinwardly, toward the center ofthe lock,by the spring 21, which is alsofastened to the inner side of the flange and tends to keep the detentengaged with the bow hook, positively locking the bow, as can be seen inFig. 3. y

The detent 19 is held in looking engagement by means of the tumbler 22,shown in Fig. 3 in an unlocked position, but which can be so revolved asto prevent the detent from turning on its pivot 20. The tumbler can beturned by the stem 2d attached to dial 23, which is rotatably mounted onthe cover 14:, by means of its corrugated edges, the dial being providedwith lined characters which can be brought into registration with a markon the surface of the cover.

A further locking means, preventing the detent 19 from turning on itspivot, is provided by the T or L shaped stop extending through the sideflange and having an operating block 26 rigidly engaged with it in suchmanner that when the block edges of the stands parallel with the sidesof the lock body the stop 25 will register with, and enter intodepression 86, formed in the edge of the detent 19, as the detent ismoved in a direction to unlock the how; but when the block is in itsnormal position, that is transverse to the edge of the lock, the stopwill not enter the depression but by reason of its angularly turnedportions acts to prevent the detent from moving. A similar block 27 ispivoted on the opposite edge of the lock and both blocks are providedwith lugs 28 and 29 respectively which engage normally withcorresponding depressions in the end of the swinging bar 30, which ispivoted at its center 31 on the face or cover of the lock plate 1 1.

The function of the bar is to hold the blocks 26 and 27 in their propertransverse position and also to impart an initial turning effect to themwhen the bar is rotated, as indicated in Fig. 1. When the blocks are soturned, parallel with the sides of the lock, and the tumbler rotated bythe dial into its open position, the lock can be opened by exertingpressure upon the pin 82, the enlarged inner end 33 of which abutsagainst the lower end of the detent 19, causing the latter to turn onthe pivot 20 and disengage the hook 18, whereupon the how 12 opens underthe pressure of the spring 17, the projection 16 contacting with thefixed stop 34, which also prevents the bow from entering the lock to anexcessive depth. Thus there is provided a padlock having three distinctmeans for holding the bow in an engaged position, each means requiringseparate and, distinct manipulation to accomplish unlocking.

Having thus described the invention, itsconstruction, functions and use,'What' I claim as new and desire to secure by Letters Patent is a r 1.In a: padlock, the combination With a body, a boW pivoted therein and anopen hook formed with said boW, of a detent engageable With said hook,said detent having a longitudinal recess formed in its outer edge, meansfor disengaging said detent, a rotatable stop normally preventing saiddisengaging means fromoperating and means for registering said stop Withthe mentioned recess whereby said disengaging means may be operated.

7 limited, an

how, a pivoted detent engageable with sand casing, a sto engagement bysaid stop.

2. In a padlock, the combination with a casing, of a shackle-bow pivotedtherein, said bow having a part whereby its motion-is open hook formedWith said hook, plates pivoted on the sides of said combined with one ofsaid plates operatively engageable with said detent, a bar pivot-ed onthe face of said casing for actuating said plates and means foractuating said detent when released from LOUIS Goie s of this' patentmaybe obtainedsfor five cents each, by addressing the Comm ss r Patents,
